Planting steps:

- Backfill with excavated soil (mix in some compost if poor); firm gently.
- Water thoroughly to settle soil.
- Stake if needed (especially in exposed sites) and use a rabbit/deer guard.
- Mulch 5–8 cm deep around the base (keep clear of the trunk).
- Aftercare: Water regularly in the first 1–2 growing seasons during dry spells. Keep the base weed-free. Minimal pruning required (remove dead/damaged wood.
